Biodiversity is the degree to which species vary throughout the environment. It is used as a measure of an ecosystem's health. Biologists and ecologists who study biodiversity typically look for the number of species and the way in which species differ. They also study the distribution of biodiversity across the globe and trends that may be contributing to decreased biodiversity.

The period since the emergence of humans has displayed an ongoing biodiversity reduction and an accompanying loss of genetic diversity. Named the Holocene extinction, the reduction is caused primarily by human impacts, particularly habitat destruction. Conversely, biodiversity impacts human health in a number of ways, both positively and negatively. W

A wildlife garden (or wild garden) is an environment that is attractive to various forms of wildlife such as birds, amphibians, reptiles, insects, mammals and so on. A wildlife garden will usually contain a variety of habitats that have either been deliberately created by the gardener, or allowed to self-establish by minimising maintenance and intervention.

Many organic gardeners are sympathetic to the philosophy of wildlife gardening, and will usually try to incorporate some aspects of the wild garden into their own plots in order to both act as a means of biological pest control, as well as for its value in promoting biodiversity and generally benefitting the wider environment.

International Animal Rescue, animal welfare non-profit organization based in the United Kingdom that comes to the aid of wild and domestic animals with hands-on rescue and rehabilitation. International Animal Rescue returns rehabilitated animals to the wild while also providing permanent sanctuary for those that cannot be released. International Animal Rescue specializes in comprehensive sterilization and vaccination programs for stray dogs and cats, particularly in developing countries. They also work to educate the public in the humane treatment of all animals. International Animal Rescue has offices in the United Kingdom, United States, India, Indonesia, Malta and the Netherlands.
